Not to send this discussion in a different direction, but Andy is correct in that Maxon, while they offer their own, very strong, integrated rendering engine, they are very helpful to any 3rd party solution developers. They do this with all facets of their application. They seem to understand that their users like to have options, even if we don't all take advantage of them. As a dedicated user, t's nice to see that Maxon ownership has not chosen to create an island of their product.
